An object-oriented Library Management System developed in Java to demonstrate software engineering principles, clean architecture, and efficient library resource management.
Library Management System is a console-based Java application developed to demonstrate Object-Oriented Programming (OOP) concepts and software engineering best practices.
The system simulates the workflow of a real library where books can be managed, members can register, borrow books, return books, and monitor book availability.
This project focuses on writing clean, maintainable Java code while applying OOP principles and Java Collections Framework.
